Fix for the SetVarType / SetVarTypeNull

string: if it is stringable in anyway, set string (it converts)
this is not check IF it is a string value as it was before
int/float: same, if it is numerc it will be convert to int or float
All other stay the same

Note "set ..." imply to set, and not to convert to 0 if it is int
string that can be covnerted to int
